York S1-024-25836-700 Contactor

The York S1-024-25836-700 Contactor is a heavy-duty 1-pole definite purpose contactor engineered for high-cycle applications in residential and light commercial HVACR systems. Operating with a 120V coil voltage and rated for 30 Amp inductive load (40 Amp non-inductive), this component features normally open (1PNO) contacts designed specifically to manage power delivery to compressors and condenser fan motors. This OEM replacement ensures proper electrical sequencing, mitigating the risk of contact pitting or welding under high-amperage startup conditions. The silver cadmium oxide contacts maintain low resistance across the poles, while the compact frame allows for straightforward integration into existing control boxes. Whether you are performing a seasonal preventative maintenance check or responding to a failed startup relay, the S1-024-25836-700 provides the necessary durability to handle the inrush current of typical split-system cooling units.

• Reliable Switching: Single-pole design with a shunt for continuous circuit paths where needed in 1-pole configurations.

HVAC Tech - Common Questions

Can I use a 24V coil contactor to replace the S1-024-25836-700?
No. The S1-024-25836-700 requires a 120V control signal. Using a 24V coil in its place will prevent the magnetic field from engaging the contacts, while using a 24V signal on this 120V coil will fail to pull in the armature.

What are the signs of a failing York 30 Amp contactor?
Look for excessive "chattering" during startup, burnt or discolored contact points, or a total loss of continuity across the poles when the 120V coil is energized. High resistance at the contacts often leads to compressor motor overheating.

Is the S1-024-25836-700 compatible with other brands?
Yes, as long as the 30A inductive rating, 120V coil, and 1PNO configuration match the original specifications. It is frequently utilized in Source 1, York, Coleman, and Luxaire equipment.
